摘要：

The explicit compact difference scheme,proposed in Three-point explicit compact difference scheme with arbitrary order of accuracy and its application in CFD by Lin et al.,published in Applied Mathematics and Mechanics(English Edition),2007,28(7),943-953,has the same performance as the conventional finite difference schemes.It is just another expression of the conventional finite difference schemes.The proposed expression does not have the advantages of a compact difference scheme.Nonetheless,we can more easily obtain and implement compared with the conventional expression in which the coeffcients can only be obtained by solving equations,especially for higher accurate schemes.
